ICE CREEPER Filed March 30, 1939 Patented Dec. 5, 1939 UNITED STATESPATENT OFFICE 4 Claims.

This invention relates to an ice creeper for attachment adapted for useon overshoes primarily, to aord traction and prevent slipping whenwalking on ice.

A particular object is to provide such a construction as issubstantially embedded in the sole of the overshoe, practically out ofsight, which is light in weight, durable and eihcient and capable ofbeing adjusted so that its spurs will either be projected or retractedas preferred.

The more specic objects and advantages will become apparent from aconsideration of the description following taken in connection with theaccompanying drawing illustrating an operative embodiment.

In said drawing:-

Figure 1 is a fragmentary bottom view of an overshoe equipped with myimprovement;

Figure 2 is a side elevation of the parts of Figure l;

Figure 3 is a vertical sectional view taken on the line 3 3 I'of Figure2;

Figure 4 is a detail section showing the projected and retractedpositions of the spurs;

Figure 5 is a plan View of the device alone, and

Figure 6 is an elevation of the traction element alone.

Referring specically to the drawing wherein like reference characters.designate like or similar parts, the invention is shown for example inconnection with an overshoe generally designated I0 and being of anysuitable material, for instance rubber and rubberized fabricconstruction. Such illustration is to be taken as but one example of anarticle in connection with which the invention may be used, since it maybe applied, where practical, to all articles likely to be worn on a footor a shoe. Said overshoe I I! includes the usual sole II.

Embedded in the sole II and disposed transversely thereof is a metallicmounting plate I2, preferably of relatively light weight in view ofnumerous perforations I3 therethrough. Such plate adjacent its outerportion is widened as at I4 and then formed into an upstanding wall I5,terminating in an outwardly projecting ange I6. It will be noted,particularly from Figures 2 and 3, that the wall I5 is disposed in thesole II relatively close to a marginal edge thereof and that it projectsthrough the latter at the ridge I 2, where the upper is cemented to thesole. The

n ilange I6 extends outwardly relatively close to said ridge.

Said plate I2 mounts a traction element generally designated I1. Suchtraction element I1 has a rod portion I8 disposed longitudinally of theplate I2 and journaled in bearings I9 of such plate, preferably beingstruck out portions bent over the rod I 8. Rod I8 has depending spurs 29operable in slots 2| of the plate I2, and clear- 5 ance recesses 22provided in the sole Il, below the slots and plate. Such spurs areadapted to be projected to the full line position shown in Figures 2, 3,4 and 6 to afford traction to the wearer or when traction is notdesired, they may be 10 moved ino the dotted line position shown inFigures 2 and 4, being thus retracted above the sole or walking surface.The spurs preferably have an angular portion 23, which in projectedposition as shown in Figure 4, will abut the plate 15 I2 at one edge ofthe adjacent slot ZI to enhance its support.

In order to secure the traction member in either projected or retractedposition, it is provided with an operating arm 24 of resilient mate- 20rial. Cooperating with the arm 24 is a pair of notches 25 and 26provided in the outer edge of the flange I5. The resilience of arm 24urges the same into engagement with the notches 25 and 26 when inregistry therewith and when en- 25 gaged with the former, the spurs willbe retracted and when engaged with the latter, the spurs will beprojected. It will be realized, that in moving the arm 24 from one notchto the other, that the same must be sprung slightly to disengage the 30adjacent notch, but will through its resilience snap into a notch whenregistered therewith.

Various changes may be resorted to provided they fall within the spiritand scope of the invention.

I claim asl my inventionl. A shoe article of the class described havinga plate embedded in a sole, a wall on said plate extending upwardly andoutwardly primarily located within the sole, and a traction member 40mounted on the plate for movement to and from projected position, andcoacting means between the traction member and wall to secure thetraction means in its different positions. v

2. A shoe device of the class described having 45 a plate embedded inits sole, a` wall on said plate within the sole extending upwardlyadjacent one margin of the sole, a flange extending outwardly from saidwall and exteriorly of the sole, a traction member pivoted on saidplate, said traction 50 member having spurs extending therefrom andthrough the plate, and an operating means for the traction member havinglatch engagement with said flange.

3. A shoe device of the class described having 55 a plate embedded inits sole, a Wall on said plate within the sole extending upwardlyadjacent one margin of the sole, a ange extending outwardly from saidWall and exteriorly of the sole, la traction member pivoted on saidplate, said traction member having spurs extending therefrom and throughthe plate, and an operating means for the traction member having latchengagement With said ange, consisting of a resilient arm on the tractionmember and notches in said flange into Which the arm is adapted to snap.

4. A shoe device of the class described having a plate embedded in itssole, a Wall on said plate Within the sole extending upwardly adjacentone margin of the sole, a flange extending outwardly from said Wall andexteriorly of the sole, a traction member pvoted on said plate, saidtraction member having spurs extending therefrom and through the plate,and an operating means for the traction member having latch engagementwith said flange, consisting of a resilient arm on the traction memberand notches in said flange into which the arm is adapted to snap, saidplate having notches through which the spurs extend, said spurs havingangular portions to eieot engagement of the spurs in projected positionwith a Wall of the plate for reinforcement.
